Abstract
A cluster and a cluster are linked by a link frame. The link area includes postamble, post guard, and a slice/PLL area, as well as a link data area. Substantially the same data as that recorded in clusters is recorded in the link data area. The capacity of a rewritable disc can thus be increased.
Claims11
A disc in which data is recorded along tracks, said disc comprising:
- a plurality of data blocks of a first size, each having a plurality of sectors of a second size, being formed on said tracks;
- and
- link areas of said second size formed between respective data blocks;
- wherein
- each link area includes a start point as a recording start position and a pre-specified random amount of position shift data following said start point.
A disc in which data is recorded along tracks, said disc comprising
- a plurality of data blocks of a first size, each having a plurality of sector data of a second size being formed on said tracks;
- and
- link areas of said second size formed between respective data blocks;
- wherein
- said track is comprised of at least one wobbling groove modulated corresponding to address information including a track number and a segment number designating a circumferential direction.
A disc in which data is recorded along tracks, said disc comprising:
- a plurality of data blocks of a first size, each having a plurality of sectors of a second size being formed on said tracks;
- and
- link areas of said second size formed between respective data blocks;
- wherein
- each of said sectors comprises a plurality of frames having frame synchronization signals which are selected from among frame synchronization signals of plural types and are disposed in a specified order, and each of said link areas includes frames disposed in such an order that frame synchronization signals thereof are equal to said frame synchronization signals of said sectors.
A disc in which data is recorded along tracks, wherein:
- said disc has the same frame structure as a reproduce only disc in which sectors of data are comprised of a plurality of frames having respective specified frame synchronization signals;
- and
- a link area is formed between adjacent sectors, said area including frames disposed in such an order that frame synchronization signals thereof are equal to said frame synchronization signals of said sectors.
A device for recording data in a disc, said device comprising:
- a head for recording data on tracks formed in said disc and reproducing the data recorded on the tracks;
- and
- a recording circuit for outputting input data to said head in units of data blocks having a first size and adding a portion of link areas having a second size before and after the data blocks for output;
- wherein
- each link area includes a start point as a recording start position and a pre-specified random amount of position shift data following said start point.
A device for recording data in a recordable disc having the same frame structure as a reproduce-only disc in which sectors of data are comprised of a plurality of frames having respective specified frame synchronization signals, said device comprising:
- a head for recording data on tracks formed in said disc and reproducing the data recorded on the tracks;
- and
- a recording circuit for outputting input data to said head in units of data sectors and adding link data between the adjacent data sectors, said link data having frames disposed in such an order that frame synchronization signals thereof are equal to said frame synchronization signals of said data sectors.
